Bioelectrical impedance analysis for an endangered desert fish—Data

These data were used to examine the effectiveness of a non-lethal tool (Bioelectrical Impedance Analysis, "BIA") to estimate the physiological condition of endangered and threatened fishes in the Colorado River Basin. We conducted laboratory trials using hatchery-raised Humpback Chub and Bonytail and wild-captured Roundtail Chub, where fish were subjected to different feeding trials to...

Water classification of the Colorado River Corridor, Grand Canyon, Arizona, 2013—Data

These data area classified maps of water in the Colorado River at a discharge of approximately 227 meters squared/second in Grand Canyon from Glen Canyon Dam to Pearce Ferry in Arizona. The data are derived from interpretation of multispectral high resolution airborne imagery that was acquired in May 2013. The water classification data have the same 0.2-meter ground resolution as the imagery....

Metabolic-hydaulic model Data

The data contained in this workbook were compiled to investigate the relationship between hydrology of the Colorado River and ecosystem metabolism parameters (i.e., primary production and ecosystem respiration). The workbook contains data exploring the link between Colorado River discharges and water velocity, which are depicted in figure 2 of the associated manuscript. The workbook also

Desert Tortoise Ecology and Precipitation, Mojave and Sonoran Deserts—Data

These estimated precipitation data were compiled using the WestMap web site (http://www.cefa.dri.edu/Westmap/). We selected pixels on the map shown on their web site that were in the core of our study areas: one near Palm Springs, California and the other at Sugarloaf Mountain in the Tonto National Forest of Arizona. WestMap uses PRISM data to...

USGS 2017 BRalston Ground Dwelling Arthropod Composition Data v3

These data were compiled from pitfall traps deployed at three sites, along a 25 kilometers (km) stretch of the Colorado River, immediately downstream of Glen Canyon Dam, in Glen Canyon National Recreation Area. Each site had both pre and post-dam riparian habitats present. The purpose of the sampling was to determine if arthropod abundance, diversity and feeding guilds differed betwee

Body size estimates for slider turtles in the United States, 1944-2010——Data

Table 1, compiles data from published studies of various subspecies of the slider turtle (Trachemys scripta) from throughout the native range of the species in the United States. Data include sample sizes of adult male and female turtles as well as various estimates of their body size as noted in the Comments column.

Community-level riparian plant traits, Colorado River, Grand Canyon, 2013-2015

These data were compiled based on field observations and available literature. Field observations of plant cover were made in September and October of 2013 and 2014, while trait measurements were made in September and October of 2014 and 2015. Field data was collected on sandbars along the Colorado River through Grand Canyon between river miles 0 and 226. Field measurements of specific leaf...

Climate, Wildfire, and Erosion Data, Western US

These data were used to examine how post-fire sedimentation might change in western USA watersheds with future fire from the decade of 2001-10 through 2041-50. The data include previously published projections (Hawbaker and Zhu, 2012a, b) of areas burned by future wildfires for several climate change scenarios and general circulation models (GCMs) that we summarized for 471 watersheds

USGS 2017 AKasprak Geomorphic Process Topographic Form—Data

These data were used for the development and validation of the automated workflow for mechanistic segregation of geomorphic transport mechanisms presented in the manuscript "Geomorphic Process from Topographic Form: Automating the Interpretation of Repeat Survey Data in River Valleys." These data include (1) raster digital surface models (DSMs) from 2002, 2009, and 2013 of seven

Grand Canyon Whitewater Boater Data, Temporal Stability of Willingness to Pay Values

These data were complied for the primary analysis underlying the resuts presented in Neher et al., Testing the Limits of Temporal Stability: Willingness to Pay Values Among Grand Canyon Whitewater Boaters across Decades. The data is a combination of data collected for a 1985 survey of private party Grand Canyon boaters, and a 2015 replication survey for that same recreational user group.
